Erigeron aphanactis grows in sage, scrub, and open woodland habitat. It is a short, clumping perennial with stem and foliage covered in stiff hairs and resin glands. Most of the narrow, fuzzy leaves are near the base of the plant. The erect stems hold inflorescences of one or more flat, buttonlike flower heads, which contain numerous golden yellow disc florets but no ray florets. Each head is about 10 mm (0.4 inches) wide.[5]
